Abstract

An algorithm is discussed which translates two-dimensional mathematical expressions such as subscripting and displayed division, that have been prepared using a keyboard input device, into a string form suitable for input to a classical compiler. The algorithm allows reasonably general forms, yet is sufficiently simple to be practically applicable today. It may be used as a preprocessor to an existing compiler in order to improve the readability of an existing language.
